TWID is back for 2014 - hope you had a good break. Due to the holidays, this is a catch-up edition so may contain some older news.
The Dart Editor and SDK on the DEV channel were updated to 1.1.0-dev.5.6. The current push is towards a 1.1 release. The numerous updates are detailed here - dart:io and server side related functionality is moving forward.
Sticking with WebGL and gaming, check out Alphabets - 'Alphabets is a game designed for young children learning alphabets.The game supports English, Finnish and Norwegian languages'.
Hope you are planning to build something great with Dart in 2014!
